This square is important for many reasons, not just because it is the closest stop to our boat station! Here, under a glass footpath, you can see the ruins of what was the first settlement of Pest, the Roman Contra Aquincum fortress. The first Roman soldiers arrived around 45 AD and gradually the city of Aquincum grew around the fortress until by the second century it had a population of 30-40 thousand inhabitants and covered much of what is now the Obuda District. It is believed that Marcus Aurelius wrote at least some of his Meditations here.

Many centuries later, the square was known as Oath Square as Emperor Franz Joseph took his oath here. Now, of course, it is named to commemorate the beginning of the Hungarian Revolution of 1848. The church dominating the square is a lovely Baroque church built in 1725 to replace a Gothic 14th century church that was destroyed by fire.
